Title: Load driving circuit
IPC: H03K19/003
Filed: 1992-03-12
Abstract: PURPOSE:To attain quick charge/discharge drive to a capacitive load whose load state changes between a high load and a small load without causing a breakdown of an output transistor(TR). CONSTITUTION:A load driving circuit 1 connects to a load capacitor Cl via a totempole load driving circuit 10 and a coupling capacitor C1 and consists of a leading characteristic control circuit 20 having a circuit acting like a constant current circuit. The totempole load drive circuit 10 applies a high speed charging/discharging to the load capacitor Cl in a high load state. When the load capacitor Cl is small, if the leading characteristic of the totempole load drive circuit 10 is too steep and a sustain voltage of a transistor(TR) is going to be decreased, the leading characteristic control circuit 20 is activated to limit a collector potential of a phase splitter use TR Q3 an delays the operation of TRs Q4, Q5 thereby slowing down the leading characteristic and preventing occurrence of breakdown of the TRs.

Title: Inspection device for picture by electron ray
Inventor: UTAKA MASATOSHI
IPC: G03F1/86
Filed: 1979-07-13
Abstract: PURPOSE:To increase the extracting speed of picture informations effectively by a method wherein a plurality of picture elements are magnified by an electronic optical system and simultaneously detected by a plurality of detectors. CONSTITUTION:Electrons irradiate a fixed area on a sample 7 through a trottle 2 and electromagnetic lenses 3, 4. The electrons are modulated on the surface of the sample, and the components in the horizontal direction of reflected electrons are magnified by an electromagnetic lens 8 and collide with a detector array. The reflected electrons are made binary 11 through respective independent amplifiers 10, and informations are processed, displayed and stored by a computer 12. Electron beams pass through the lens 4, and are electrostatically deflected 5 in the direction that is vertical to the surface of paper, and the reflected electrons synchronize with a moving base 13, are electrostatically deflected 6 in the direction that is reverse to the base 13 and are projected to the electromagnetic lens 8. The deflection 5, 6 is synchronized in the directions that are mutually reverse. According to this constitu tion, since two-dimensional pictures are transmitted to an information processing system partially and simultaneously, this method is close to a human pattern recognizing method, and is advantageous for increasing the speed of information processing and heightening its accuracy.

Title: High pressure resisting semiconductor integrated circuit device
Inventor: TAKAHASHI SHIGERU
IPC: H01L21/76
Filed: 1979-07-13
Abstract: PURPOSE:To enable high withstand voltage without changing a process by a mechanism wherein slits are formed to an upper portion of a channel stopper of wiring crossing the upper portion of the channel stopper. CONSTITUTION:Slits 10 are formed into a Al wiring film 8 only of an upper portion of an N<+>-layer 9 for a channel stopper. Consequently, Al wiring on the layer 9 is apparently regarded as a plural strip of Al wiring, whose wiring width is thin. Thus, field concentration in a channel stopper portion is moderated, field strength at the center of wiring is decreased in the same manner as the case when wiring width is narrow, and pressure resistance is improved. As a result, high withstand voltage is enabled without changing a process.

Title: Semiconductor pressure converter
Inventor: TAKAHASHI MINORU
IPC: G01L9/00
Filed: 1981-06-10
Abstract: PURPOSE:To reduce zero fluctuation of output voltage at high temperature and moisture for high performance, by forming a diaphragm used for a semiconductor pressure converter into the one not subject to the stress variation effect due to the moisture absorption at the junction of an Si chip and glass base. CONSTITUTION:The thin diaphragm 5 is formed on the back surface of the Si chip 1 by silicon etch with an SiO22b as a masking for anode junction to the glass base 6. Pressure on the diaphragm 5 causes the diaphragm to be strained with the resistance value of a strain gauge 3 varied by piezo resistance effect. Then, the diaphragm is formed into a rectangular octagon. Thus, the zero fluctuation of output voltage is reduced without decreasing the sensitivity to the pressure of the strain gauge 3 in high temperature and moisture atmosphere.

Title: Welding method of cu-ni-si alloy
Inventor: MORI SHIGENOBU
IPC: B23K9/23
Filed: 1979-07-13
Abstract: PURPOSE: To prevent the weld crack of the time when joining and welding the titled alloy material of the specific composition along and a restraining material by preheating this alloy to the specific temperature prior to welding etc.  
     CONSTITUTION: The Cu-Ni-Si alloy comprising ≤1.1% Si based on weight, ≤4.5% Ni and Cu and unavoidable impurities for the remainder is preheated to ≥TP°C of the formula prior to welding. Here, γ denotes the maximum amount of silicide that can be deposited in that alloy. Next, this alloy alone or this alloy and a restraining material of, for example, stainless steel, is joined by pressure contacting and are welded. When the Si and Ni in the alloy to be welded exceed the above-described amounts respectively, weld crack is apt to occur despite preheating to a predetermined temperature. If the preheating temperature TP is below the above-described value, rupture draw decreases and the crack along the crystal grain boundaries of metal structure is shown by the action of tensile stress.

Abstract: PURPOSE:To efficiently discharge ozone by turning on/off a fan for discharging ozone in synchronism with the timing of turning on/off a scanner motor for scanning a photosensitive body with laser light. CONSTITUTION:The fan for discharging the ozone 5 is turned on by a control means 2 in synchronism with the timing of turning on a rotary polygon mirror for scanning the photosensitive body with the laser light, that is, the scanner motor 3, and the fan 5 is turned off in synchronism with the timing of turning off the motor 3. When the scanner motor 3 is turned on, an image forming process progresses, high voltage is generated and the ozone evolved at the time of generating the high voltage is discharged by the fan 5 which is driven simultaneously. Since an image forming process is also finished when the motor 3 is turned off, the ozone is not evolved thereafter. Therefore, there is no trouble even when the fan 5 is stopped simultaneously. Thus, the ozone is efficiently discharged.
